Create an open, modern aquascape with the Real Reef Nano Arches six-pack in the dramatic Midnight Black finish. Each box includes six individually handcrafted arches sized for nano aquariums, shallow displays and detailed aquascaping projects.

The preformed arch design makes it easy to create bridges, caves, tunnels, overhangs and elevated coral platforms without filling the aquarium with bulky rock. The dark finish provides a high-contrast foundation that helps colorful fish and corals stand out under aquarium lighting.

Aquascaping Possibilities

Use the six arches together to create a complete nano reef structure or place them individually throughout a larger aquarium. Multiple arches can be connected with reef-safe glue, epoxy or aquarium mortar to create multi-level formations and interconnected swimming areas.

The arches also work well as dedicated coral islands for zoanthids, Goniopora, encrusting Montipora and other corals that may need to be separated from the main rockwork.

Recommended Aquarium Size

These nano arches are especially well suited for aquariums between approximately 10 and 40 gallons. They can also be used as accent pieces, bridges or coral platforms in larger displays.

Preparation and Cycling

Rinse each arch thoroughly with RO/DI water before placing it in the aquarium to remove dust created during packaging and transportation. This rock arrives biologically sterile and must be properly cycled or seeded with beneficial bacteria before livestock is introduced.
